TENSION AND FEED MECHANISM FOR WIRE-FABRIC MACHIINES.

SPECIFICATION formingpart of Letters Patent No. 628,915, dated July 18, 1899.

I Application filed. January 21, 1899. Serial No. 702,922- (No modelfi) T0 at whom it may concern:

Be it known that I, HERBERT S. BIssELL, a citizen of the United States, residing at VValkerville,county of Essex, Province of Ontario, Canada, have invented a certain new and useful Improvement in Tension and Feed Mechanism for Wire Weaving or Fabric Machines; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, which form a part of this specification.

My invention relates to an improved tension and feed mechanism for wire Weaving or fabric machines upon which the wires are passed to other mechanism by which the strands of the wires are woven or united. In machines of this nature it is desirable and requisite that tension and feed mechanism should be provided to hold the wires so that they shall feed with uniformity and be prevented from slipping or feeding one faster than another to the weaving or analogous mechanism for uniting the wires. If there be but a slight variation in the feeding of the wires, the difference is liable to become considerable in a long length of fabric or in feeding to the machine a coil of wire of ordinary size.

It is the object of my invention to prevent and to secure a superior degree of uniformity in the feed by my improved tension and feed mechanism.

To these ends my invention consists of the structures hereinafter described and claimed, and illustrated in the accompanying drawings, in Which- Figure 1 is aview in side elevation, showing parts in section. Fig. 2 is a detail view in inverted plan, illustrating a feature of my invention. Fig. 3 is a detail view, in end elevation, of the tension device embodied in my invention. Fig. 4c is a view, partly in section and partly in elevation, on the line 4 4., Fig. 1. Figs. 5, 6, 7, 8, and 9 are fragmentary views of the rim of one of the revolumyself, however, to any given number of such guides.

As shown, the guideor wheel is constructed with a series of radiating arms or spokes, (indicated at A,) with the extremities of which the rim A? of the guide or wheel is engaged. The periphery of the guide is channeled in any suitable manner, as indicated at a, to receive and hold from lateral displacement a strand of wire C, bent thereover from any suitable source of supply.

The guide or wheel A is provided with a series of clamps D, which may be constructed each with a clamping-j aw D, given a normal spring-tension'upon the wire C in any suitable manner, as by a spring D which spring may be secured upon the arms or spokes A. The jaws D are shown f ulcrumed, as at D upon ears cl upon the guide or wheel, said ears being formed integrally therewith, or otherwise, as may be desired. The jaws D, at their outer ends, are so formed as to normally contact with and firmly grip the ad jacent wire C upon the periphery of the guide or wheel within the channel a. The clamps D are preferably located upon the lateral face of the guide or wheel, the rim of the wheel being cut away laterally adjacent to the jaw, as shown at a, to admit the outer end of the adjacent jaw. It will be seen that the tension-clamps D are carried with said guide or wheel in its rotation. The springs D it will be understood, are of the required tension to To disengage the clamps at a proper point in the rotation of the guide, any suitable device may be cmploycd-as, for example, a cam E, supported in any suitable manner in such a position that the inner extremities of the jaws D will contact therewith in the rotation of the guide to depress the adjacent end of the jaw and thereby lift the outer end of the jaw to release the wire. In Fig. 4, at the bottom of the figure, one of the jaws is shown in position to release the wire, while the upper end of said figure shows a corresponding jaw gripped upon the wire. The cam may be of any suitable shape, but preferably constructed so that the jaw will ride suddenly off therefrom to reengage the wire, which will result if the cam is constructed with a straight face, as at c, Fig. 2. The jaw in riding off the cam will of course be reengaged upon the wire passing onto the guide or wheel from the source of supply.

My invention contemplates employing a tension device to hold the wire 0 taut in passing from the source of supply to the tension guide or wheel A. Such a device is shown in Figs. 1 and 3 of the drawings at F, and may consist of a channeled support F, on which the wire is passed to the tension wheel or guide. One or more dogs F each mounted upon a support F is arranged to grip upon a passing wire. To this end the dogs F may be curve -shaped, as shown, and provided with a tension-spring F In case the periphery of theguide or wheel were not at all points concentric, or in case it might be desired to increase or diminish the diameter of the guide or to increase the radius from the base of the channel a of the guide at any given point, my invention contemplates the employment of an adjusting device for that purpose. To this end, G indicates a bolt threaded into the rim of the wheel in a radial direction and provided with a jam nut g. (Shown in detail in Fig. 5.) The outer end of the bolt projects adjacent to the base of the channel a in the periphery of the wheel or guide. By adjusting the bolts G more or less diameter at that point can readily be given to the guide, either to compensate for any lack of uniformity in the construction of the Wheel or to increase or diminish the total diameter of the wheel or guide, as may be required. Instead of a bolt threaded radially into the rim a bolt may be threaded laterally thereinto, as indicated at H, carrying an eccentric H thereupon, as indicated in detail in Figs. 6 and 7. It is evident that in this latter device the eccentric can be thrown out into the channel a as may be required.

In Fig. 8 is shown in detail another modification in the construction of the device for enlarging the diameter of the wheel. In this latter case the rim of the wheel may be separated at a desired point, as indicated at a Fig. 8, and a wedge Jbe employed to expand the rim, or vice versa.

As indicated in Figs. '1 and 9, a tapering bolt K may be insertod'into the lateral face of the wheel to expand the rim, a nut K being employed on the opposite side of the rim.

The operation of the invention will readily be understood. The operation of the various parts is simple, while the tension and feed mechanism as a whole is not liable to get out of order, but will exert such a tension upon the wire or upon the series of wires as contemplated within my invention in a superior and efficient manner.

That I claim as my invention is 1. In a tension and feed mechanism for a wire weaving or fabric machine, a revoluble tension-guide channeled on its periphery and cut away on a lateral face of the guide, and a tension device normally projecting into the t-away portion of the guide to grip the wire, substa tially as set forth.

2, I a, tension and feed mechanism for a wir w aving or fabric machine, a revoluble t n i ide to carry a wire over its periphery, a jaw fulcrumed on a lateral face of the guide to grip the wire, and a spring to exert its tension upon said jaw, substantially as set forth.

3. In a tension and feed mechanism for a wire weaving or fabric machine, a revoluble tension-guide, a series of spring-tension clamps located upon a lateral face of the guide, and a releasing device located adjacent to said lateral face of the guide, substantially as and for the purpose set forth.

4. In a tension and feed mechanism for a wire weaving or fabric machine, a revoluble tension-guide, a support over which the wire is passed to said guide, and a spring clamping-dog to grip the wire upon said support, substantially as set forth.

5. In a tension and feed mechanism for a wire weaving or fabric machine, a revoluble tension-guide formed with a rim and channeled on its periphery, a clamping-jaw fulcrumed upon a lateral face of the rim, and a spring at the inner end of the jaw to give the jaw normal tension upon the wire passed over the periphery of the guide, substantially as set forth.

6. In a tension and feed mechanism for a wire weaving or fabric machine, a revoluble guide channeled onits periphery,and a spring clamp carried upon a lateral face of the guide to grip a wire in said channel, said guide cut away adjacent to said clamp to permit the clamp gripping the wire, substantially as set forth.

In testimony whereof I sign this specification in the presence of two witnesses.

HERBERT S. BISSELL.
